CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract—The goal of this research was to assess the consistency of source code comprehension strategies and comprehension effort estimation metrics, such as LOC, across different types of modification tasks in software maintenance and evolution. This metrics include the following − 1. On a more granular level, software development managers are trying to: 1. However, the maintenance of software systems is also risky and costly. When development of a software product is complete and it is released to the market, it enters the maintenance phase of its life cycle. IEEE have proposed Software Maturity Index (SMI), which provides indications relating to the stability of software product. Design metrics – computed from requirements or design documents before ... source, or they are producing data for another module ! For the maintenance activities, metrics have been designed explicitly. Raw source lines of code (SLOC) is the oldest, easiest, most basic metric there is. Enabling / disabling analysis of system headers, Specifying which static analysis metrics to calculate (through an options file), Specifying the source files, functions or classes to be analyzed, Specifying precisely the source code statements to be analyzed (through pragmas in the source code).

source code metrics in software maintenance

0 1

Lots of people were having lots of fun writing measurement programs until some spoilsport did the obvious study, and demonstrated that each and every single Halstead metric was strongly directly correlated with SLOC. Metrics for source code: These assess source code complexity, maintainability, and other characteristics. Abstract. 2. For example, we can calculate the mean McCabe Cyclomatic Complexity value for all functions or methods within our system. A software metric is a standard of measure of a degree to which a software system or process possesses some property. Software metrics are necessarily computed on the structure of the source code. This article outlines code ownership and its impact on quality and shows the results of two studies we … Resources for measuring and assessing software quality. How can metrics, like for example (Executable?) Static code analysis, code complexity, lines of code (LOC) Of these four, performance is probably the one that is easiest to measure. 172–181. IEEE Transactions on Software Engineering 24, 491–496 (1998), Heitlager, I., Kuipers, T., Visser, J.: A Practical Model for Measuring Maintainability. Source code copying for reuse (code cloning) is often observed in software implementations. The new command-line code metrics tool computes metrics even in the presence of source code errors, as long as the solution and project can be loaded. Cite as. Software metrics are used to obtain objective reproducible ... Code metrics ! Customer Satisfaction Because the new Metrics.exe tool is source code-based, command-line code metrics results are different to those generated by the Visual Studio IDE and by previous versions of Metrics.exe. The following are some of the most significant and useful software metrics of the latter type.

In Proceedings of the 9th India Software Engineering Conference (2016), ISEC '16, pp. Product Metrics:These are the measures of various characteristics of the software product. The goal of tracking and analyzing software metrics is to determine the quality of the current product or process, improve that quality and predict the quality once the software development project is complete. Number of modules in current release (MT) 2. Let’s understand what is test coverage and how it is evaluated in the general terms. May ultimately involve increased system maintenance costs. Examples are the Maintainability Index [16], the CK metrics, including coupling and cohesion [5] and various code smells [9]. The goal is to reach 100%. These include: All metrics are provided at the function, class, translation unit, or system level, as appropriate. Defect detection percentage. The AST is a tree-based representation of the tokens contained in the source code. Romano, D., Pinzger, M.: Using source code metrics to predict change-prone Java interfaces. 184–190. Google Scholar Digital Library; Li, W., and Henry, S. Maintenance metrics … Cantata provides over 300 source code metrics on C/C++ which provides useful objective measurement and visualisation of non-functional qualities of the source code: Measurement of non-functional qualities involves the static inspection of the source code in order to provide an assessment of various non-functional features relating to the software, and is invoked on a build of a Cantata enabled software project. OOMeter is an experimental software metrics tool developed by Alghamdi. Some of these metrics, such as Lines of Code and Comment Ratio, have a fairly obvious meaning and use; most are less self-explanatory. They are extracted from the source code of … Organisations are increasingly adopting coding standards as a means of improving software quality and maintainability. Moreover, earlier studies suggest that in … Over the years, many metrics have been devised for analyzing software source code. The following metrics are therefore very important: Fix backlog and backlog management index. Having some heuristics and metrics that measure an application’s source code provides a useful starting point, and observing these metrics over time can identify important trends. Switch statements with no defaults or fallthroughs, Number of GOTO statements, used and unused GOTO Labels. 16–31 (2004), Ferenc, R., Beszédes, Á., Tarkiainen, M., Gyimóthy, T.: Columbus – Reverse Engineering Tool and Schema for C++. 368–377. For example, the maximum nesting levels within functions is also applicable to class methods. Defect density. Plotting graphs of the data can aid understanding and create overall pictures of the trends occurring lower down that are not immediately obvious when you are reading the metrics as numbers alone. Security Issues —fixing security vulnerabilities found in your proprietary code or third-party code, especially open source components; Software Quality and Maintainability. He also describes the key metrics used by several major software developers and discusses software metrics data collection. Number of new methods plus overridden methods defined for this class. Code quality and test coverage metrics are two important metrics which comes in play during software testing. Code complexity and structure. It accepts Java/C# source code and UML models in XMI and calculates various metrics. This is the proportion of source code that automated tests cover. Percent delinquent fixes. Source-code metrics are related with software developer activity to gain insight into developer-specific effects on software code quality. Software quality and code quality can make a world of difference for software maintenance. Metrics for maintenance: These assess the stability of the software product. Maximizing the potential of these metrics ultimately depends on the systems and processes put in place by facilities. The popular ones include MOOSE (Metrics for OO Software Engineering), MOOD (Metrics for OO Design), and QMOOD (Quality Metrics for OO Design). Number of statically unreachable statements in the given scope. To find source code similarities among different files of a software system, plagiarism and clone detection techniques are used.

The 4 Hidden Costs of Code Maintenance Page 2 Summary Code maintenance has grown to become the largest budget item in most software development organizations [1][2]. Although, a lot of researches analyze the relation of source code metrics to other objective measures, only a few studies deal with their expressiveness of subjective feelings of … The number of classes with which this class is coupled (via a non-inheritance dependency from this class to that, or vice versa). NEWS: McCabe Software Honors Top Rhode Island Finishers in Annual Cyber Security Challenge. Chidamber & Kemerer’s Response for a class metric. 52.1.165.57. Software Reverse Engineering is the process of recovering the design and the requirements specification of a product from an analysis of it’s code. Metrics visualisation can be plotted at the class, function or category level. Chidamber and Kemerer’s MOOSE metric set. To help answer such questions, much of software engineering research over the years has been devoted to software maintenance metrics. Reverse Engineering is becoming important, since several existing software products, lack proper documentation, are highly unstructured, or their structure has degraded through a series of maintenance efforts. Source code metrics . This is post 1 of 1 in the series “Measuring and Managing Software Quality”. If poor quality software produced quickly, may appear to be more productive than if produce reliable and easy to maintain software (measure only over software development phase). 151--155. These software development metrics assess defects and vulnerabilities. Those changes are necessary to add new features, to adapt to a new environment, to x bugs or to refactor the source code. Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics… DatrixTM, a source code analyzer tool set [S]. Grafana is an open source analytics and monitoring platform designed for every database. A decision tree based classifier achieved a precision of over 76% during the estimation of the Changeability ISO/IEC 9126 attribute.

IEEE Computer Society (October 2002), Ferenc, R., Siket, I., Gyimóthy, T.: Extracting Facts from Open Source Software. Such code cloning causes difficulty when software functionalities are modified: i.e, cloned codes increase the maintenance cost of software. The vast majority of existing quality models use source code metrics for measuring low level quality attributes. Maximum length of inheritance path to ultimate base class. Metrics computed at module level: Source Lines of Code (SLOC) Noncommented Source Lines of Code; Comment Lines; Number of Methods; Decision Density; Cyclomatic Complexity; Maximum loop nesting; Maximum conditional nesting; Halstead measures (volume, difficulty, effort, operators and operands) Software Engineering Institute (SEI) Maintainability Index As Cantata can produce over 300 static metrics on source code, below are some examples of specific metrics and their most useful application. Size and complexity of software. © 2020 Springer Nature Switzerland AG. Software Metrics MCQ. Part of Springer Nature. Process Metrics:These are the measures of various characteristics of the software development process. × The McCabe Cyclomatic Complexity value for the function. While Cantata is not a coding standards rule checking product, it does provide the developer with static analysis metrics on the use of several useful coding constructs such as: Understanding how complex the source code is, can be very helpful for estimating how long it will take to test it. Number of non-empty case blocks which fall through to the next case block. Once the metrics have been gathered by Cantata they can be processed and manipulated using an add-in for Microsoft Excel. The number of methods or functions defined in the class or called by methods of the class. It’s the simple type of code analysis when the software is inactive. High quality benchmarking leads to a greater understanding of where a company is on the best practices ladder to measure against historical performance, company goals or “world class” metrics. In addition to helping measure data acquisition efforts, this metrics also measures a maintenance team’s degree of organization. 30–39 (2007), International Organization for Standardization: ISO/IEC 15504:2004 Information technology – Process assessment – Part 3: Guidance on performing an assessment. We aim to estimate the maintenance cost caused by clones. Abstract Context Source code metrics are essential components in the software measurement process. In: Proceedings of the 18th International Conference on Software Maintenance (ICSM 2002), pp. The verification estimates stack usage from the function call hierarchy and local variable sizes. : A Validation of Object-Oriented Design Metrics as Quality Indicators. : A Metrics Suite for Object Oriented Design. Proportion of attributes that are hidden (private or protected). An SSCA supports other maintenance tools which interact with source code by creating a data base of source information which has links to a formatted version of program source code. This is a new capability that parses TPS source code and extract metrics that leverages other sources of data, such as log data and UUT maintenance data. Searches can be performed for patterns in a specific language, or patterns across languages (such as "find identifiers involving TAX"). Fix response time and fix responsiveness. pp 272-284 | At the code level, developers can tabulate the number of defects per KLOC to assess the frequency of defects. The ‘OO’ aspects of the C++ language have tended to render the old procedural C metrics less useful, but fortunately new sets of metrics have taken their place. Software Download: If you are new to Imagix 4D, the best way to understand the tool is simply to try it.Because Imagix 4D is so visual and interactive, reading textual descriptions and studying static screen shots are poor substitutes for actually running the tool itself. These are simple metrics regarding the number of lines of code, comments, etc. 303–312. However, unless these standards can be verified in an automated way, it is difficult to enforce them effectively. Configuring the analysis can be achieved through the following methods: Code quality and complexity metrics provided by Cantata can help users to determine areas of the code that will most likely suffer from bugs, as well as producing data from which the time required for testing can be estimated. If poor quality software produced quickly, may appear to be more productive than if produce reliable and easy to maintain software (measure only over software development phase). Cantata source code metrics use industry standard complexity metrics to accurately estimate the testing effort for source items. source code metrics as an effective instrument to control the internal quality of software systems. Total number of lines of code (including blank lines and comments). The quality of a piece of software is to some degree based on the number of occurrences of dubious code contained within it. These two aspects of testing are interrelated but there is no direct formula to evaluate in terms of each other. In: Proceedings of the 6th International Conference on Quality of Information and Communications Technology, pp. Software metrics is a standard of measure that contains many activities which involve some degree of measurement. Cantata supports code complexity metrics on procedural source code as a means of increasing the maintainability of software, through objective measurement using recognised ‘academic’ and common sense metrics: In addition to code complexity measures for object oriented code, Cantata also provides a number of metrics which measure aspects of object oriented implementation. That is, the more the LoC -> the more the bugs -> the worse the quality. Level of coupling between objects. Software metrics have been proposed for measuring many, many different aspects of an existing body of source code. Basic counts of language constructs (comments, lines of code, statements, parameters etc). Increase return on investment (ROI) 2. The other three are tricky to quantify and while metrics exist, they do not show the complete picture.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract—The goal of this research was to assess the consistency of source code comprehension strategies and comprehension effort estimation metrics, such as LOC, across different types of modification tasks in software maintenance and evolution. This metrics include the following − 1. On a more granular level, software development managers are trying to: 1. However, the maintenance of software systems is also risky and costly. When development of a software product is complete and it is released to the market, it enters the maintenance phase of its life cycle. IEEE have proposed Software Maturity Index (SMI), which provides indications relating to the stability of software product. Design metrics – computed from requirements or design documents before ... source, or they are producing data for another module ! For the maintenance activities, metrics have been designed explicitly. Raw source lines of code (SLOC) is the oldest, easiest, most basic metric there is. Enabling / disabling analysis of system headers, Specifying which static analysis metrics to calculate (through an options file), Specifying the source files, functions or classes to be analyzed, Specifying precisely the source code statements to be analyzed (through pragmas in the source code). May ultimately involve increased system maintenance costs. Common measures: Lines of source code written per programmer month. Cantata supports code complexity metrics on procedural source code as a means of increasing the maintainability of software, through objective measurement using recognised ‘academic’ and common sense metrics: Halstead’s Software Science metrics.
